The Cl− ions in the of NaCl lattice structure are present at:
Open in App
Solution
In NaCl,Cl− ions forms fcc structure lattic. Thus, Cl− present at the corners and face centres of the cube.
Here, Na+ ions occupies all the octahedral voids. The octahedral voids are present at the edge centres and body centre of the unit cell.
The coordination number of NaCl is 6:6
